An instance of NSDeleteCommand deletes the specified scriptable object or objects (such as words, paragraphs, and so on).

Suppose, for example, a user executes a script that sends the command delete the third rectangle in the first document to the Sketch sample application (located in /Developer/Examples/AppKit). Cocoa creates an NSDeleteCommand object to perform the operation. When the command is executed, it uses the key-value coding mechanism (by invoking removeValueAtIndex:fromPropertyWithKey:) to remove the specified object or objects from their container. See the description for removeValueAtIndex:fromPropertyWithKey: for related information.

NSDeleteCommand is part of Cocoa’s built-in scripting support. Most applications don’t need to subclass NSDeleteCommand or call its methods.

Declaration

Parameters

receiversRef

The receiver’s object specifier.

Discussion

This method overrides setReceiversSpecifier: in NSScriptCommand. It performs the same function as the overridden method, with a critical difference: it causes the container specifier part of the passed-in object specifier to become the receiver specifier of the command, and the key part of the passed-in object specifier to become the key specifier. If, for example, receiversRef is a specifier for the third rectangle of the first document, the receiver specifier is the first document while the key specifier is the third rectangle.
